marty You mean manually? Yes, via the Nginx Helper plugin. Open the page you want to purge in your web browser (while logged in to WordPress), select Purge Current Page from the admin menu at the top.
marty kkumar326 Do I need to change anything in nginx conf? No. kkumar326 And is it using nginx plus cache plugin? I don't know what you mean by "nginx plus cache plugin". This is Nginx not Nginx Plus (different thing). WordOps installs the WordPress plugin called Nginx Helper (check your plugins) to manage cache clearing on publishing new content.
